To all'wwm it may concern.:

Be it known that I, JOHN C. WANDS, a citizen of the United States, residing at St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in `Metal Oar- Itoofs; and I do declare the following to be a full, clear, and exact description 'ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

, Figure l of the drawings is a representation of this invention, and shows a top View of a portion of a car-roof, part of which is broken away. Fig. 2 is a vertical section. Fig. 3 is adetail showinga section across one of the battens and washer. Fig. 4 is a detail section. Figs. 5, 6, and 7 are detail views. Fig. 8 isa detail section.

" This invention has relation to iron-covered' car-roofs; and it consists in the construction and novel arrangement of parts, all as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the framing under' thev roofboards or sheathing B.

C represents the under or inside central purlin of said framing. y

D Dare the iron roof-plates.

E is the longitudinal center bar between the ilange ends of theiron plates.

F is a metallic or felt strip extending over the comb of the roof, and covering the joints between the central bar, E, and the ends of the iron plates which abut against the same.

G represents the upper central purlin,which is fastened to the under central purlin by bolts a, which pass through the bar E, so that all parts composing the central portion othe roof are firmly connected. Byl varying the breadth of the central bar, E, the iron plates are adapted to cars of different widths without requiring any change in the length. If the bar E is madewider,the plate or covering F and the outer or top purlin, G, should also be made wider.

H represents the under longitudinal 1nolding-strip or bargeboard, which is longitudinally grooved in its upper edge, as at b, and in its lower edge, as at c. This strip extends along under the projecting edges of the roof boards or plates at the side of the car, and is designed to allow the escape of any water which may get under the plates through the grooves and vertical perforations d, forming outlets to said grooves.

K K are the roof-battens, which are placed over the sheathing. The iron-plates D are made to lap vover the battens. Each plate is formed with edge ribsd, concave underneath to fit over the battens, and these ribs d are connected at their inner ends by the upwardlyturned end iianges,c,of the plates, the ends of which are firmly soldered to the ends of the ribs; When these plates are in position lapping over the battens the upwardly-turned end iianges, 'c, abut against the center bar, E, of the roof -frame. The plates are held in position by means of screws q and clamp-bearings or cast washers l1, having downwardlycurved ends to iit the ribs`of the plates, and perforated to provide bearings for the screws. The clamps embrace the ribs of the plates, and the screws, passed through said clamps and ribs into the battens and sheathing, serve to hold the plates securely to their places.

Near the edge of the roof clamps are used which have hook-arms 7c, bent upward from the body of the clamp, and then downward, said hook-arms being adapted to engage an iron rod or safety-rail, Z, which is designed to extend along the top of the car hear its edge, as shown.

The clampwashers are countersunk in the 'upper portions of their perforations, to receive the heads of the screws, and when the attachment is made cement is put in the countersunk recess to make the joint between the screw and washer watery-tight. f

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

l. The combination, with the under and npper central purlins and the longitudinal center bar between the same, of the iron plates secured to the sheathing on each side, and having upwardly-tnrned flanges at their in- IOO ner ends abutting against said center bar, substantially as speciiied.

2. The combination7 with the under and upper central purlins and the longitudinal center bar, of the iianged iron plates abutting against the center bar, and the center strip oi' i'elting or metal under the upper pnrlin7 and covering the joints between the center bar and the iron plates, substantially as speciiied.

3. rIhe combination7 with the under and upper central purlins,the longitudinal center bar,the sheathing7 and the battens, of the iron plates having the under concave side ribs lapping over the battens7 and the end flanges connecting-'said side ribs and abutting against the center bar, substantially as specified.

4. rllhe iron rooiing-plates for ears, having' under concave side ribs and the upwardlyvln testimony whereof I ailix n1 y signature in presence of two witnesses.
